shell 脚本过滤段落内容
在研究show engine innodb status 输出信息，为了看其中的insert buffer部分信息，写了个脚本
# mysql -uroot -e 'show engine innodb status \G' |grep -E -A8 -B1 --color 'INSERT BUFFER'
-------------------------------------
INSERT BUFFER AND ADAPTIVE HASH INDEX
-------------------------------------
Ibuf: size 37064, free list len 21130, seg size 58195, 22172798 merges
merged operations:
insert 88714186, delete mark 32775614, delete 18942413
discarded operations:
insert 9204, delete mark 8597, delete 12
Hash table size 42499631, node heap has 151066 buffer(s)
3275.24 hash searches/s, 647.12 non-hash searches/s
